Earlier today, Yemeni police opened fire to stop protesters from reaching the U.S. Embassy in Saana, witnesses said (see 7:31 a.m. entry).

[Updated at 9:54 a.m. ET] Ron Hawkins, a spokesman for the U.S. Embassy in Khartoum, said that because Friday is a non-work day, most of the staff and Embassy personnel are not there as protesters gather outside the building. As far as security goes, Marines are assigned there, and local police officers were sent there earlier Friday as a precautionary measure, Hawkins said.

Earlier Friday, a fire was set at the vacated German Embassy as protesters gathered there. The protest at the U.S. building so has been peaceful, journalist Isma’il Kamal Kushkush said (see 8:42 a.m. entry).

[Updated at 9 a.m. ET] An update on protests in Egypt, while we await more information about the burning German Embassy in Sudan:

Fifteen protesters have been injured in Egypt on Friday, according to Dr. Mohamed Sultan, a health ministry spokesman. Most of the injuries were related to inhaling tear gas or getting it into their eyes.

Two hundred twenty-four people have been injured this week in protests in Cairo, 11 of whom have been hospitalized, Sultan said.

On Friday, officers armed with shields and batons, backed by an armored personnel carrier, rushed a group of several hundred protesters shortly after dawn to quell a violent demonstration that had raged through the night in Cairo. After the rush, a smaller number of demonstrators regrouped near the U.S. Embassy across from police lines, and stones and tear-gas canisters once again crossed in the air. Police fired rubber bullets at protesters. The army began constructing a wall of concrete blocks about 10 feet high across the road leading to the embassy.

Hours later, in the afternoon, youths climbed the newly built wall and threw rocks at police, according to eyewitnesses. Security forces fired tear gas and used water cannons to hold off the rioters. But 100 to 200 hundred meters away in Tahrir Square, a few thousand protesters congregated peacefully.
